sad but expected. Guts is a personification of the eclypse, a perpetuel reminder, by his body or his psyché, his armor, his weapon, etc.
It's beautifull to see Casca back, full of hop about this reunion, but everything crush when she meet him. It remind in a block all the suffering. About Griffith body, i am curious too, maybe a link between the body of Guts ? Because we don't see a glimpse of Femto, bot the broken body. Maybe the Broken falcon, the broken dream, the broken doll.
We well see, how i will turn, but Casca is happy to meet Guts, she is still in love and remember all trigger (i am not sure about the use of this word) Gut passed, and the other, to protect her. It's a good point, but the fear of him, or maybe the fear of the eclypse, the trauma, sadly Guts is the vessel of it.
The dress is a bit awkward on her, but she is beautifull like this, like a new Casca. But we reconize the old one in her eye, in this picture, when Schierke make the difference.
A hiatus, it was expected too... But we see her again, that's cool. I can wait now.
Edit : Oh, i post, but i didn't read before the resume.
So, the body of Griffith is the last glimps of her memory before the eclypse. Seing Gut, will make her remember everything. She has a black out between the end the rescue and the journey to heal her. The next time she will remember everything. We can better understang, why, during the corridor of dream we just see the eclypse in this representation, but we see a lot of the golden age. And the thorn take their meaning, this is the memory seal.
Edit : sorry, for all misuse of word, i will progress, i promess !
Edit 2 :
Another point. About the full picture of Casca in tear of joy. I am rereading Berserk, and it's about the promess of Guts, to take Casca with him. Finally he did it, he is with Casca, about all the manga, we can maybe resume Berserk about it, the story of a man who travel all the earth to heal his woman, fighting monster. It's almost a myth, a legend. She feel it, i think, that maybe he leave her a moment or not, but he is, and that the most important point, still her. He didn't leave her.
